Body control module is shorted, open or low voltage?

I got a used amp and used a y harness behind my uconnect8.4 to do the add on. Come to find out the amp had a short and now my raider has no power at the connector, but I have power at both of the radio fuses #61 in my power distribution center and my 20a in line fuse by the outer fire wall on driver side. Now I also am getting a body control module trouble code saying there’s either a short or no power to some components in the system.
